Application filed September 17, 1929; :fSerial' am i This inventionrelates generally to agricultural implements more specifically to a diskplow or furrow.

The object of this invention is to provide an implement of constructedin such a manner that the cultivating tools will be automatically raisedfrom the ground during turning movement, there-- by permitting a shortradius or right angle turn.

Other objects and advantages will be apparent from the followingdescription, reference being ings, in which:

Fig. 1 is a top plan view of the disk plow showing the parts as theyappear in working position;

Fig. 2 is a top plan view showing the position of the parts assembledwhile mak ng a turn;

Fig. 8 is a side elevation;

Fig. 4 is a sectional view taken on line 4-4 of Fig. 1 in the directionindicated by the arrows;

Fig. 5 is a sectional view taken on line 5-5 of Fig. 2 showing the disksin raised posi-q 1 tools out of the ground or furrow in order tion;

Fig. 6 is a sectional view taken on line 6-6 of Fig. 1 showing the depthadjusting 3 means;

Fig. 7 is a sectional view taken on line 7-7 of Fig. 1 showing the diskmounting;

Fig. 8 is a view similar to Fig. 4 showing the cultivating tools in araised position;

pintle 32 extending through a bearing 33 in the frame. In a similarmanner the guide wheel 16 is mounted on an axle 34 formed the characterreferred to on and secured to the pintles 32 and37-by had to theaccompanying draw Fig. 9 is a fragmentary side elevation show frameconsisting of- 21 carried by a shaft 22 integral'with a member-36 whichis provided -with a pmtle "37 mounted ina bearing 38 secured co the bar12 of the frame and'eXtencL ing upwardly therefrom.

Levers 40 and 41 respectively are mounted keys or set screws, the outerends of which are connected to a bar 44by pins 45. i

The implement is adapted to be. drawn by a tractor or other pullingmeans through a tongue 48 connected to the frame 10 by clevis 49 andbolt 50, thebar being also .con-

nected to the tongue .by apin 51"pa-ssing 7 through an opening in thebar and a slot 52 in the tongue, it bemgaunderstood that the tongue 1sadapted to be connected to the draw bar of a tractor. Y i i 1 Thetrailer wheel 18 is mounted onan' axle 53 projecting from a member-54having a pintle 55 extending through 'a bearing 56 in 7 0 the framel0,'each of the members 31, 36 and 54 having collars designated at'57,58 and .59 respectively upon which the. frame 10 v rests.

An important feature of the .inventionresides in means for lifting thecultivating to make a turn without stopping or manually operating the.usual trip devices. This is accomplished by a cam 60 secured to theupper .end of thejpintle 32by a setscrew 61, the. cam having aninclinedface 62 engaged by a roller 63.mounted on an arm 64 secured tothe shaft22.,by aset screw .65.

When making a turn the guide -wheels 8 move from the positionshown inFig. 1 to that shown'in Fig. 2 due to movement of the tongue 48 throughthe bar. 44 and levers 40 and 41. During movement of the guide wheelsthe shaft 22 will be rocked due to 9 movement at the cam 60, theinclined face 62 lifting the-roller 63, thereby raising the disks asshown in Fig. .5. I

From the foregoing it=will be seen that the disks are automaticallyraised prior to makmg a turrnthereby enabling the implement -to ineke ashort radius turn, practically at a and adapted to engage faces 7l-and72- o'nthelframe adjacentthe bearings 56.

- .:'l hezc-utting depth. of tools is regulated by By loosening the setscrew 65" on the-arm 69 then manipulating the screw 74 I the posihenmoving the implement v frombn field to another, or over roads the disksmay be; held in raised position by withdrawing runningposition as shownin F ig.r8. l I Plows designated .at 8O may be substituted J rockingmovement to a pintle mounted in a bearing secured to said g frame, asecond guide wheel'mounted on an axle projecting from said secondmember, leverssecured tothe pintles 'ofsaid first and second members, atongue pivotally connected to said frame, and a-barconnected'to saidlevers whereby movement ofsaidtongue will simultaneously turns-aid'wgulde Wheels and actuate said cam,,therebytransmitting saidcultivating tools.
